Deck Construction Permits in Round Rock

Local Rule

City of Round Rock Building Inspection Division

The city's own Other Building Permits page publishes flat fee tiers rather than a valuation formula for this project type: a wood deck or uncovered patio without electrical or plumbing costs $125, a covered patio without electrical or plumbing costs $200, and a covered patio with electrical or plumbing runs $300. A specific published deck-size exemption was not located directly on the city's own site, so the 200 square foot, 30 inch figures used here follow the general Texas IRC baseline rather than a confirmed Round Rock-specific citation. Structures must maintain a minimum 5 foot separation from side and rear property lines and stay clear of recorded easements, and the building permit fee is non-refundable and non-transferable once paid.

How This Compares to Williamson County

Round Rock's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:

Williamson County (no residential building code enforced in

Williamson County does not require any new residential construction, including a deck, to conform to any building code in its unincorporated areas. A property in a floodplain still needs a Certification of Compliance from the Road and Bridge Division for driveway culverts, and properties within a city's extraterritorial jurisdiction (ETJ) follow that city's own rules instead.
